Why Choose the Wöhner 33617 NH In-Line Fuse Switch-Disconnector?
The Wöhner 33617 is a high-performance NH in-line fuse switch-disconnector designed for safe switching, isolation and fuse protection within industrial low-voltage power distribution systems. Part of the Wöhner QUADRON® 185Power Speed series, this size 00 device combines dependable circuit protection with operator-independent switching for consistent and reliable operation.
Its integrated snap-action mechanism completes the switching movement independently of the speed at which the handle is operated. This helps provide controlled switching performance while improving safety during the isolation of electrical circuits. The high-format design is suitable for compact switchgear assemblies, distribution boards and industrial control panels.
The Wöhner 33617 features a top M8 connection and screw terminals for secure electrical installation. It is designed for mounting on 30, 40, 60, 80, 100 or 120 × 10 mm busbars, providing flexibility across a wide range of 185 mm busbar power distribution systems.

Safe Power Isolation for Industrial Distribution
NH fuse switch-disconnectors combine circuit isolation with high-capacity fuse protection. When fitted with suitable NH fuse links, the Wöhner 33617 helps protect electrical equipment and conductors against overloads and short circuits while also providing a clear means of disconnecting the circuit for maintenance.
The operator-independent switching mechanism ensures that contact movement is controlled by the device rather than the operating speed of the user. This makes the switch-disconnector well suited to demanding industrial power distribution applications where repeatable operation and safe isolation are essential.
Typical Applications
- Industrial low-voltage switchboards.
- 185 mm busbar power distribution systems.
- Main and sub-distribution panels.
- Machine and production-line power supplies.
- Motor control centres.
- Commercial and industrial electrical installations.
